Again, I own the car and you have never driven it lol.
yes only in eco setting (E) will "glide mode" activate where it basically just goes into neutral on the move and kills the engine, and afaik the car never defaults to starting in E setting so if glide mode ever does activate it's because the car was manually put there

i think it's fun sometimes! if i see a light turn red like way down the road with nothing ahead of me i might pop the selector into E to get a super long coast without any engine braking

btw i assume your W223 does this too but the GLE (450 model at least) will actually do variable regen depending on how quickly the car in front of you starts slowing down, it's almost like dynamic cruise control but only acts on the ISG... i enjoy that too since if you get the timing right you can pretty much come to nearly a full stop without having to touch the brakes, although it does involve potentially tailgating a bit closer than most would be ok with lol

Any added complexity adds to more difficult repairs. Especially in remote areas.

i've never experienced a "shudder" when the GLE does this, it's actually an exceptionally smooth engagement... if you weren't looking at the tach you really wouldn't know the engine turned back on and re-engaged with the drivetrain

Bingo!

SW's Valve Cover Gasket was gonna be what, 10 grand if paid out of warranty? It was some ludicrously stupid amount.

That's just labor bc the engine is so insanely complex. Adding all of this junk to it? Pass. Even worse.

They're actually not, if anything it reduces complexity. The issue with the 48v system is in the error processing and warning systems. They can wreak havoc from a software standpoint.

I personally don't prefer or not prefer a 48v system. The reality is though that all new cars are going to have 48v systems, and I don't want to keep driving the same car so 48v it is. I feel the same way about EVs, more and more of the attractive cars are going to be EVs, so I'm open to EVs.

Yep, I have felt the same thing...its very cool.

Thats just it, IMO this kind of improves the driving experience if anything. It fills in any turbo lag down low, and at a stop you have the total silence of an EV which is nice.

Except that adding this if anything reduces complexity...it doesn't increase complexity. Not gonna own it out of warranty anyways.

Explain to me how less wiring is more complex? And how many 48v systems has this "expert" worked on? And what does a Mercedes S Class Valve cover have to do with 48v? Opinions are OK, but uniformed ones hurt people, mainly themselves

I don't know much about "48 volt systems" on cars and what they're used for other than active suspension like posted above

But, I can see where upping to 48v can only help because smaller and lighter wires and motors can be used. It's a good thing because it helps with the higher power demands.

However, when someone says, " active suspension", I'm already expecting lots added complexity (both mechanical & electrical) when compared to dumb struts and control arms. Lol

It is more complex when the break. Not easy for any mechanic to repair. Especially outside of a dealer network. Older engines, much easier to repair and parts are available especially aftermarket etc. just obtaining a battery alone is not easy.

Well the good news is you can still buy cars that don't have things like active suspension, and save a lot of money doing so. Cars like the S-Class are never going to be lacking in complexity. A partner at my firm recently traded his Lexus in for an Elantra because he just wanted a basic car that gets him from A to B and was done with all the features. Different strokes for different folks.

just to bring things to the totally opposite end of the spectrum: the V12 of the GMA T.50 is possibly the cleanest engine design ever thanks to 48V



the ISG at the front eliminates the need for accessory belts and pulley driven pumps... for the latest, most cutting edge engine ever put into a production car it's really remarkably simple in its external appearance! gordon murray himself vouched for the 48V system and there's nobody who thinks more big picture than him in terms of a car remaining relevant and usable for the following decades

Suspension is a different animal, any type of active suspension is going to be more complex. But when when people here talk about 48v, they have no idea what they talking about. Not you, I can see you understand it

Thanks for the example. I really don't mean any offense, but people shouldn't talk about stuff they have no idea about. It just makes them look ignorant...excuse my French

EDIT

BTW, that IS the cleanest engine I've ever seen.....thanks to 48v

How and why?

Hybrids have been around for 30 years, lots and lots of regular ol' mechanics are able to repair hybrids. As hybrids get older, even more of them will learn how and be able to...they will have to in order to remain in business.

BTW, nothing on the M176 engine with or without a 48v system is easily repaired by just any mechanic. You need a specialist.
